Jiangshuai Li e3940312c1 gdb:csky add pseudo regs for float and vector regs
In the existing CSKY architecture, there are at most 32 floating
and 16 vector registers. Float registers's count can be configured
as 16 or 32. In the future, the vector registers's count may be
extended to 32.

The bit width of floating-point register is 64bits, and the bit
width of vector register is 128bit.

Special points: in fr0~fr15 and vr0~vr15, each FRx is the lower
64 bits of the corresponding VRx.

Here, we will split each floating-point and vector register to
32bits wide, add the corresponding pseudo registers, and finally
use them for the dwarf registers.

There are 128 pseudo registers in total, s0~s127, including:
1. s0 and s1 correspond to fr0, s4 and s5 correspond to fr1, and so on.
Every two separated pseudo registers correspond to a float register.
2. s0, s1, s2 and s3 correspond to vr0; s4, s5, s6 and s7 correspond to vr1,
and so on. Every four pseudo registers corresponds to a vector register.

Therefore, in s64~s127, there are general registers that are not actually
used. This part is to prepare for the expansion of vector registers to 32

Therefore, in s64~s127, half of the registers are actually unused. This
part is to prepare for the expansion of the vector register to 32.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
